Communication Protocol
The Servo motor controller is controlled through pulse width modulation.
Rotational speed and direction are determined by the duration of a high pulse,
in the 1000us–-2000us range.
In order for smooth rotation, the servo needs a 20 ms pause between pulses.
As the length of the pulse decreases from 1500us, the servo will gradually rotate faster in the counter-clockwise direction.
Likewise, as the length of the pulse increases from 1500us,
the servo will gradually rotate faster in the clockwise direction,
as can be seen in the figure below
